I get two clean ten litre buckets and fill one with about 50mm of warm water, in which I squirt a bit of soap detergent.

I strip the line from off the reel into this bucket and soak the line under the water for 20-30 minutes.

Push the line down into the soapy water but don’t swirl the line around.

After the said time or thereabouts, I strip the line out of the first bucket and into the second bucket, wiping the line through a clean micro towel which removes the residue from the line. I sometimes do this twice if the line is very grubby.

When the line is stripped into the second bucket, get rid of the soapy water and dry the first bucket. Strip the line back into this bucket.

If you just want a quick clean and you feel this is sufficient you can now place the line back onto the reel.

Every two or three times after I have washed the line I strip the line back into the cleaned first bucket. I then tip some silicon onto a cloth and strip the line into the second bucket wiping the silicon onto the fly line.

Sometimes if the line is particularly dirty I will wipe it twice with the silicon before putting back on the reel.
